Save cache data in local storage.

[AugustoL]

Each time the dapp loads it gtes the data from the cache block to the last block in the network to update the dao cache to the latest block.

Save the data fetched in the local storage, this way the data for the dapp would be dxvote cache + localstorage cache + latest data.

Importat: Dont save the data of the dapp in the cache, it is already available in the dapp, the goal here is to reduce the loading time if you enter to the app often.
